Given numbers are 345, 140, 339, 440

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 339 are 3 x 113

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 345, 140, 339, 440

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(345, 140) = 9660

GCD(345, 140) = ( 345 x 140 ) / 9660

= 345 / 140

= 345

Step2:

LCM(5, 339) = 1695

GCD(5, 339) = ( 5 x 339 ) / 1695

= 5 / 339

= 5

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 345, 140, 339, 440 is 1
